FORD 2001 E-450 - Manual (Page 23)

• NORM A/C-Uses outside air to cool the vehicle. It is quieter than MAX
A/C but not as economical. Airflow will be from the instrument panel
registers.
• VENT-Distributes outside air through the instrument panel registers.
However, the air will not be cooled below the outside temperature
because the air conditioning does not operate in this mode.
• OFF-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
• FLR-Allows for maximum heating by distributing outside air through
the floor ducts. However, the air will not be cooled below the outside
temperature because the air conditioning does not operate in this
mode.
• MIX-Distributes outside air through the windshield defroster ducts and
the floor ducts. Heating and air conditioning capabilities are provided
in this mode. For added customer comfort, when the temperature
control knob is anywhere in between the full hot and full cold
positions, the air distributed through the floor ducts will be slightly
warmer than the air sent to the windshield defroster ducts. If the
temperature is about 6°C (43°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
• DEF
-Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
temperature is about 6°C (43°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
Operating tips
• In humid weather conditions, place the climate control system in DEF
before driving. This will reduce fogging on your windshield. Once the
windshield has been cleared, operate the climate control system as
desired.
• To reduce humidity buildup inside the vehicle in cold weather
conditions, don’t drive with the climate control system in the OFF or
MAX A/C position.
• To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF
position.
